Assistant manager Colin Pascoe deputised for the sick Brendan Rodgers as Liverpool brushed QPR aside 3-0 and he was delighted with the performance of the team.
Rodgers was taken ill in London, with back-up goalkeeper Brad Jones and head of performance Glen Driscoll also sent home with the virus.
But the side flourished in their absence, two predatory Luis Suarez strikes and Daniel Agger settling the issue in 13 devastating first-half minutes.
"This morning he phoned me at eight o'clock," said Pascoe of Rodgers. "I wasn't feeling very well myself this morning, but he's worse than me.
"The way the medical team and the doctors tried to isolate the players and the staff, they've been fantastic.
"Hopefully they'll have nipped it in the bud and not too many will be affected by it.
"All of the lads were magnificent. The chances we created were phenomenal. We could have had a couple more. Some of our play was exciting to watch and I'm sure our fans will be happy tonight.
"It was fantastic to watch, the way the lads passed the ball around and the weight of our chances."
